Rasmussen College: NURSING 2502/MDC3
Final Exam Study Guide_ Latest 2021/2022
• Left Sided Heart Failure (left side: backs up into the lungs)
Left atrium, Left ventricle, mitral valve, or aortic valve
o Ejection fraction needed to dx LHF <40
o Causes: HTN, Coronary artery disease (CAD), valvular disease
o Education: restrict sodium, and possible fluid restriction, daily weight
(report 2lb in 1 night or 3-5lb in 1-week weight gain), report sleep
sitting up, use pillows to prop themselves up, notify provider is
increase swelling, and decreased activity tolerance, med compliance
(no skipping Lasik’s)
o Signs and symptoms: increased BP and pooling of blood, pink frothy
sputum, dyspnea and night, crackles, fatigue, pulmonary congestion,
crackles, wheezing
o The main goal is to prevent exacerbation in chronic conditions
o Diagnosis: Ejection fraction (echocardiogram), Lab: BNP (fluid
overload), Chest Xray, ECG
o Interventions: Oxygen, position, assess lung sounds, assess VS,
cough, and deep breath
o Tx: DASH Diet,
▪ Medications: Overall goal is to manage fluid volume and help
the heart to control the fluid volume that is there.
• Diuretics ---- Enhance selective excretion of various
electrolytes & water
o Loop: furosemide: monitor potassium and
electrolytes, dehydration (monitor daily weight and
I&O, skin turgor, MOITOR BP before giving). If
IV push give slowly. Adverse effects: Tinnitus
(chronic)
o Thiazide: monitor potassium, possible supplements
o Potassium Sparing- Spironolactone: Monitor
POSTASSIUM – This is potassium sparing.
• Ace inhibitors (-pril)
• Arbs
• Beta Blockers (-olol): lowers HR
• Heart Failure in General
o Education: monitor daily weight, stay active, low sodium diet,
possible fluid restrictions, Med adherence, avoid NSAID (can lead to
sodium and fluid retention)
o What labs do you monitor for HF: BNP (if elevated anticipation that
diuretic because it is showing that the heart is stressed, and it shows
that more fluid is on the heart)
o Best tool for dx of HF in general- Echocardiogram. This looks at the
blood flow
Difference between Left and Right HF: Left backs up into lungs, right
backs up into the rest of you. Right side of heart is systemic edema.
Left side is pulmonary edema and the left will lead to the right. Know
the signs and symptoms of each and the differences between them
o What else leads to heart failure in general: HTN, valve disorders, cor
pulmonal, smoking, DM, A Fib, MI.
o PRIORITY IS ALWAYS YOUR ABC’s.
o End stage heart failure, the last treatment would be a transplant. They
will also be on the LVAD. Education post-transplant:
immunosuppressant (avoid large crows, infection, do not eat raw fish
or meat, no fresh flowers hand washing, lab and med adherence,
watch for low grade fever), confusion
o Hypertension with right sided HF, Hypotension with left sided HF
• Right sided heart Failure
o RF: Left sided HF (left ventricular failure), Right ventricular MI,
Lung disease, Pulmonary Hypertension, pulmonary fibrosis
Right atrium
Tricuspid Valve
Right ventricle
, Pulmonary valve
Signs and symptoms: abdominal ascites, peripheral edema, JVD,
weight gain, fatigue, nocturia
o Diagnosis: Echocardiogram, Lab: BNP (best lab), electrolytes, H&H
o Manifestations: Positive JVD, increased ascites (and girth),
hepatomegaly (congestive liver), Nausea, Vomiting, peripheral edema,
malaise, enlarged liver and spleen, anorexia, dependent edema,
distended jugular veins,
o Tx: Same as Left sided HF, unless the cause is dt lung disease, then
we will be tx lung disease.
o CHF has an S3 gallop (this can be normal in athletes)
• Mitral Valve Prolapse
o This is on the left side of our heart, between the left atrium and
ventricle.
o If this prolapses it means the valve leaflets are going to fall back into
left atrium
o Usually benign, it can progress to mitral valve regurgitation
o You will hear this as a murmur in the heart
• Valve Stenosis
o Narrowing of the valve causing a decrease in amount of blood that can
flow through. Blood then backs up into lungs.
o This can lead to left sided heart failure
o The valves become stiff, which can narrow the valvular opening
, o Blood will back up and cause hypertrophy of the left ventricle. They
will have HF manifestations dt back up of blood. They may also have
A. Fib or clots
treatment
diuretics, blockers, Ca+ blockers
o Presents with an S4 gallop
• Mitral Valve Regurgitation
o The backflow of blood into the left atrium, causing hypertrophy of left
atrium and ventricle because not all the blood is leaving the heart.
Causes
• Rheumatic fever
• Infective Endocarditis
• Papillary muscle dysfunction
o This can lead to heart failure.
Signs and symptoms
tachycardia, fatigue, weakness, high pitched murmur, neck pain,
pooling of blood that leads to edema and JVD (this is dt it is backing
up into the lungs and then further into the right side of the heart
causing symptoms of right sided HF)
Treatment
similar tx for HF; diuretics, low sodium diet, decreased overall
volume, surgery to repair or replace valve.
o You will hear this as a murmur in the heart.
o If manifestations of hf occur, they may discuss procedures to repair
valve.
